摘　　要：本文简介了流场的概念以及心腔流场的研究技术,着重介绍了血流向量成像技术(VFM)的临床应用,包括左心室流场、右心房流场、肺静脉流场、左心耳流场、主动脉弓流场的观察,主动脉瓣反流的定量评估,定量体肺流量比Qp/Qs的准确性,评价房间隔缺损(ASD)、动脉导管未闭(PDA)患者左室腔涡流特征等。This paper introduced a concept of flow field and research technique for cardiac flow field. We mailnly reviewed the clinical application of vector flow mapping （VFM） on the Left ventricular diastolic and systolic flow transition, flow pattern in right atrium,pulmonary vein,left auricle and aortic arch.The quantification of aortic regurgitation,feasibility and accuracy of VFM in Qp/ Qs was analyzed. Left Ventricular Vortex Analysis in ASD and PDA Patients was evaluated..
